London: Oscar winner actress Reese Witherspoon had to face denial when she first came to Hollywood.

The 35-year-old star who always wanted to be a doctor like her father, says “Acting just happened to her but later realised she is good at it”.

"You have to be focused and tough because it takes a tenacious personality to deal with rejection. When I first came here, all I heard was, 'No, not right, not tall enough, not pretty enough, not smart enough'. But I didn't really care about their opinions. I'm stubborn," Reese added.

Witherspoon won an Academy Award for her portrayal of Johnny Cash's second wife, singer June Carter, in the 2005 biopic 'Walk the Line'.

The 'Water For Elephants' star said , "Winning the Oscar makes you feel, 'Oh gosh, I have to live up to that,' and it's difficult because as an actor you're at the mercy of other people creating opportunities for you to work.”
